I have a Sculpfun S9. The stock controller board, a Sculpfun XY DLC V1.1 quit showing up as a laser device in Lightburn after I tried to add limit switches.
I purchased a Makerbase MKS DLC V2.1 as a replacement and it registers as a USB Serial controller when I run lsusb but will not show up as a laser in Lightburn.
I have flashed the firmware with the GRBL stock firmware but still no joy.
I’m running Ubuntu 22.04.2 LTS
Did you remove brltty? This is a common problem with Ubuntu 22. You can remove it using
sudo apt-get purge --auto-remove brltty
The full documentation and another workaround can be found here: Setting up the software - Diode Laser Wiki I also created a short video of the process and linked it there.
britty wasn’t installed. I tried to configure the laser manually as suggested and Lightburn couldn’t connect. How can I tell which port the usb device is using?
do a “ls /dev/tty*” in the console once with the laser connected and once without. You should see which device is added. You can also use lsusb and dmesg to get more detailed output, but the first should be sufficient.
